Description

Technical Field

[0001] This utility model relates to the field of metal processing auxiliary equipment technology, specifically to an alignment and positioning fixture for metal sheet stacking processing. Background Technology

[0002] In the metal sheet processing industry, metal sheet lamination is a very common and critical processing method. It has the significant advantage of processing multiple sheets at once, and therefore it has been widely used in many fields such as aerospace.

[0003] Alignment and positioning fixtures for metal sheet lamination are important auxiliary equipment in this process. Their main function is to ensure that multiple sheets remain precisely aligned during processing, which plays a crucial role in ensuring processing accuracy and product quality.

[0004] Traditional alignment and positioning fixtures for metal sheet lamination often suffer from slow positioning speed and low accuracy due to their simple structural design, lack of intelligent and automated design, and inflexible positioning adjustment mechanisms. During the positioning process, traditional fixtures often require significant manual time for repeated adjustments and debugging to achieve a barely acceptable positioning effect. This not only greatly reduces production efficiency but also easily leads to positioning accuracy deviations due to the uncertainty of manual operation. When dealing with sheets of different sizes and shapes, traditional fixtures struggle to adapt and adjust quickly and accurately, failing to achieve precise positioning of the sheets in multiple directions and angles. This makes the sheets prone to misalignment and displacement during lamination, severely affecting processing accuracy, leading to product quality defects, and even product scrapping, resulting in economic losses for the company. Therefore, there is an urgent need for an alignment and positioning fixture for metal sheet lamination to solve these problems. Utility Model Content

[0032] Please see Figure 1-5 A metal sheet stacking processing alignment and positioning fixture includes a square guide rail 1 and a sheet 8 placed on a work panel 6. The square guide rail 1 is hollow inside and has a protrusion 11 at the bottom of the inner opposite side. Two sliding guide rails 2 are slidably arranged on the protrusion 11 inside the square guide rail 1. Each sliding guide rail 2 has a positioning element 3 slidably arranged inside it.

[0033] The sliding direction of the positioning component 3 is perpendicular to the sliding direction of the sliding guide rail 2, and a limit hole 21 is provided on the sliding guide rail 2;

[0034] The positioning component 3 includes a sliding part 31 and a rotating part 32. The rotating part 32 is rotatably connected to the bottom end of the sliding part 31, and the rotating part 32 makes rolling contact with one side of the plate 8 through the through limiting hole 21.

[0035] In this embodiment, each sliding guide rail 2 is provided with two positioning parts 3, and the rotating parts 32 on the two positioning parts 3 on the same sliding guide rail 2 roll in contact with the adjacent sides of the plate 8.

[0036] It should be noted that this design can form a bidirectional positioning constraint, applying positioning force from two adjacent directions of the plate 8 simultaneously, effectively preventing the plate 8 from rotating or tilting in the processing plane, ensuring that the plate 8 is precisely aligned between layers when stacked, laying the foundation for subsequent high-precision processing.

[0037] In this embodiment, an elastic telescopic rod 4 is provided between the sliding parts 31 of the two positioning members 3 on the same sliding guide rail 2.

[0038] It should be noted that when there is a slight deviation in the size of the plate 8 or when it is affected by external forces during processing, the elastic telescopic rod 4 can automatically extend and retract to adjust, so that the rotating part 32 is always in close contact with the adjacent sides of the plate 8, ensuring the continuity and stability of positioning and adapting to the positioning needs of different specifications of plates 8.

[0039] In this embodiment, an electric push rod 5 for driving the sliding guide rail 2 to move is provided on the square guide rail 1.

[0040] It should be noted that the electric push rod 5 features precise control and rapid response, and can accurately set the moving distance and speed of the sliding guide rail 2, thereby automating and standardizing the positioning process, reducing errors caused by manual operation, and improving production efficiency.

[0041] In this embodiment, the working panel 6 is provided with a guide groove 61 that moves in the same direction as the sliding guide rail 2, and a positioning sleeve 7 is slidably disposed on the guide groove 61.

[0042] It should be noted that the guide groove 61 provides a sliding guide rail 2 for the positioning sleeve 7, ensuring that the positioning sleeve 7 moves in an accurate direction.

[0043] In this embodiment, the positioning sleeves 7 are respectively fitted on the two opposite corners of the plate 8 and the plate 8 is fixed by bolts 71.

[0044] It should be noted that the diagonal fixing method can evenly distribute the positioning force, avoid excessive local stress on the plate 8 and deformation, and at the same time, the bolt 71 fixation ensures that the positioning sleeve 7 is firmly connected to the plate 8, prevents the plate 8 from loosening during processing, and ensures processing accuracy.

[0045] In this embodiment, shims are provided at the four corners of the bottom surface of the square guide rail 1.

[0046] It should be noted that the shims can absorb equipment vibration and reduce the impact of vibration on the positioning fixture. The level of the square guide rail 1 can also be finely adjusted by adjusting the thickness of the shims to ensure that the entire positioning fixture is in a stable and level positioning state.

[0047] In this embodiment, two electric push rods 5 drive two sliding guide rails 2 to move in opposite directions, and the four rotating parts 32 are all located on different sides of the plate 8.

[0048] It should be noted that this four-way positioning method can quickly and accurately position the board 8 to the center of the work panel 6, and apply positioning force to the board 8 from four directions at the same time, ensuring that the board 8 is accurately positioned in each direction and improving the quality of the lamination process.

[0049] In summary, this alignment and positioning fixture for metal sheet lamination automates the positioning process by using an electric push rod 5 to drive the sliding guide rail 2, greatly reducing manual intervention and avoiding the time-consuming and error-prone manual adjustments, thus effectively improving positioning speed. Simultaneously, the sliding guide rail 2 and the positioning component 3 work together to allow the positioning component 3 to flexibly adjust its position, precisely conforming to different sides of the sheet 8, quickly adapting to sheets 8 of different sizes and shapes, achieving multi-directional precise positioning, and ensuring processing accuracy and product quality.

[0050] This alignment and positioning fixture for metal sheet stacking processing uses an elastic telescopic rod 4 between the sliding parts 31 of the positioning member 3 to allow the two positioning members 3 on the same sliding guide rail 2 to adapt to the slight dimensional changes on the adjacent sides of the sheet 8, ensuring tightness and stability of rolling contact. The positioning member 3 is fitted onto the diagonal sides of the sheet 8 and fixed with bolts 71, stabilizing the sheet 8 from multiple angles and preventing misalignment or displacement of the sheet 8 during processing, further improving the positioning effect and product quality of sheet 8 stacking processing.

[0051] Working principle: When this alignment and positioning fixture for metal sheet lamination is in operation, the sheet 8 is first placed on the work panel 6. The electric push rod 5 is activated, which pushes two sliding guide rails 2 to move towards each other on the protrusions 11 inside the square guide rail 1, causing the positioning element 3 to synchronously approach the sheet 8. The rotating part 32 of the positioning element 3 contacts the side of the sheet 8 through the limiting hole 21. The two positioning elements 3 on the same sliding guide rail 2 are adaptively adjusted by the elastic telescopic rod 4, ensuring that the rotating part 32 is tightly fitted to the adjacent sides of the sheet 8.

[0052] Then the motor is turned off, and the positioning sleeve 7 moves in the same direction as the sliding guide rail 2, gradually fitting onto the two opposite corners of the plate 8. The positioning sleeve 7 is then fixed to the plate 8 with bolts 71 to further stabilize the plate 8. The four rotating parts 32 are located on different sides of the plate 8, positioning and clamping the plate 8 from four directions. During processing, the electric push rod 5 retracts, along with the sliding guide rail 2, to create a safe processing position for the plate 8.

[0053] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
